Used in contrast with and excluding fu'ivla. Includes all cmavo, gismu, lujvo, and non-cmevla cmene (experimental or otherwise, so long as they obey the proper form). It arguably might include cmevla, rafsi, or words which seem morphologically Lojbanic (such as zi'evla that seem Lojbanic, but probably excluding fu'ivla); as such, usage must be careful and clear. Such words must conform to phonotactic and morphological rules of Lojban.
